. This invention relates t-o boxes to be occupied by birds for layingtheir eggs and hatching and feeding their young, the box being built inform to be attached to the walls 5 of building's or to the trunks oftrees or to columnsorposts. V i

The object of the inventionis to produce such a box including an uppersection and a lowersection, the lower section being removgl able forcleaning and for observing and studying the eggs and young birds and toatford opportunity to band young birds. 1 Another object is to producea-bird box, the entrance of which may be easily; closed, 1 whereby thebox is made a trap to allow access to the brooding bird for banding, orto allowca'pturing English sparrows, starlings, or othe'r pest birds. Vp 7 Another object of the invention is to make the .bottom'or lower partof the box adjustable,,whereby the interiordepth of the box may be madesuitable forditferent kinds of fbirdspr gbirds building nests indifferent forms.

,2 o fAnotherobject of theinvention is toprovide.ample.indirectventilation for the interior otthe boxwi'thoutadmitting rain or snow. 7 i

In the accompanying drawings,

v.z -Fig, 2 is "an upright section through the dooror port; g

. "Fig. 3 is a horizontal section'on the line,

'2 of Fig. 2;

f Fig. 4 is a horizontalsection on theline, sew n i Referring to thedrawings, 1 is the upper orouter section of the bird box; and 2 is theloweror inner section. The section, 2,

telescopes into the-section,-1. The drawings show these two sections incylindrical form;

it but it-isto be understood that they may be of "other form'iin crosssection. The upper sec- 135 tion has a top wall, 3, placed to fill thespace within'th'e' upper part of the upright wall of Jtheupper sectionand secured by gluing or nailing; Usually it is desirable to make theupright wall-f this section of thin or light 1' 7 material, while'thetop wall, 3, is made thicker, to give stability to that section. Thesection, 2, has a bottom, 8, fitted within the upright wall and securedby glue or nailing. I

The upright walls of each section may be made of sheet metal or wood orordinary paper, or tar building paper. The latter is suiiicicntlydurable and is inexpensive- Such tar paper is easily shaped and is to alarge extent weather proof.

The upper section has a hole or port, 9, placed high enough to leave itabove the up- I per edge of the lower section at all times exceptingwhen the lower section is to be moved upward for trapping the birdorbirds. Said section, 1, is secured against the upright supportingmember, 7, which extends downward below both sections to allow layingthe memher, 7, flatwise against any wall or tree trunk upper end of themember, 7, and across the p .or post, or similar stationary object, andthere securing the member, 7, by nails or screws extending through theholes, 15, in said upper end of the section, 1, and has its edgesprojecting forward and laterally beyond the section, 1, far enough toserve in part to protect the section, 1, from rain. This plateissuitably secured to any or all of the members on which it rests.

The lower section is sh0Wn. provided with means for supporting it on themember, 7.

As here shown, a nail, 12, or other projecting member is driven partwayinto the base of the section, 2,'in position to adapt it to rest onnails, 13 01*.14, or other projecting members extending outward from oneface oithemember, 7, the nails on the member, 7,

being at different elevations, the lowest being low enough to allowsetting the section, 2, at what is to be its lower limit, and the nail,14, being at a height which will cause :the upper edge of the section,2, to cover the tions. This circulation of air will tend to keep theloweror lnner section cool, even though the sun shines on and heats theupper or outer section. Thus the outer section serves as a coolingjacket for the inner section. It will be noted that building andoccupying the nest will not interfere with this air passage.

It is to be noted that, by providing the removable lower section, theinterior of this bird box may be inspected while the box is placedhigher than would be permitted the upper part of the box were'hinged-togiv ac cess to the interior. My improved to: need be placed only lowenough to permit 're'a'chihg the lower end of the lower section by thehand when the arm is stretched upward, And the supporting member, 7,may; in many cases, be attached without the use of a ladder, the member,7, preferably reaching downward far enough for insertthe nails or screwsthrough the lower part of'the member, 7. For this purpose the member, 7,is preferably provided with the holes, 15, "to receive "screws in placeof nails, in order that the "structure may afterward be detached andagain attached elsewhere.

I claim as my invention:
